The ads in question offer priority to discovery, and will attempt to target users and display brands and business relevant to their interests and behaviours.

Facebook has envisioned a ‘click to Messenger’ ad placement, wherein consumers will be able to tap on an ad and immediately be transported to a one-on-one conversation with the marque or business in question. Brands will be able to leverage sponsored messages to further reach out to consumers who have previously interacted with them.

Facebook has clarified that Messenger users will only see ad placements on the app’s home screen, and further that adverts won’t display directly within the line of a conversation. Users will, of course, be given the opportunity to hide and report certain ads as they can on Facebook’s core platform.

The expanded test of Messenger ads will likely be compelling for advertisers seeking to engage with the platform’s one billion users – Facebook’s core network recently reached the milestone of attracting two billion monthly active users.
